실험 절차

Compound 6 (2.00 g, 3.62 mmol) was dissolved in 1,2-dichloroethane (60.0 ml), and 5-fluorouracil (0.71 g, 5.46 mmol) and N,O-bis(trimethylsilyl)acetamide (5.37 ml, 21.7 mmol) were added to the solution, followed by refluxing for one hour. After the reaction mixture was allowed to cool to room temperature, trimethylsilyl trifluoromethanesulfonate (0.85 ml, 4.70 mmol) was added thereto, followed by stirring overnight at 50° C. A saturated aqueous solution of sodium hydrogencarbonate was added to the mixture, and after stirring, the organic layer was dried over anhydrous magnesium sulfate. The residue was purified by means of silica gel column chromatography (silica gel 300 ml, eluent; n-hexane:ethyl acetate=3:1), to thereby yield a colorless viscous compound (Compound 31; 0.80 g, 1.28 mmol, 35.4%).
